The video which was shot in Scotland by Chinese tourists and was sent to paranormal writer Michael Cohen has been described by the writer as one of the "clearest" paranormal images he ever came across.
The ones who shot the video did not notice the Princess until they played the video when they got back home."The footage is currently being examined by myself and other researchers to ascertain if it is a genuine ghost capture. It might be a bizarre optical illusion, but then again, it could be a ghost - possibly Princess Diana's," said Michael Cohen.
"Ghosts often appear in places connected to their lives and families. Ghosts might appear to warn individuals, groups and even entire nations of possible impending danger," he said.
The footage will be used in TV series-Paranormal mysteries.
